Document Summary
Motor control studies: concerned with understanding the processes responsible for the acquisition, performance and retention of motor skills: motor means movement. Levels of analysis: knowledge about motor control is gained through inference: control mechanisms, description, measurement of movement, neurophysiology: focuses on understanding the function of the system. Studying neurophysiology: tracing nerve connections, measuring metabolic activity, evaluation of behavioural effects of brain damage, observation of behavioural effects of electrical, chemical or magnetic stimulation. Cognitive science approach: development of conceptual models to explain the behaviour of the nervous system: use experimental tasks with altered movement demands to test models, evaluate from measures of movement outcome and pattern. Components of nervous system: sensory receptors, motor units (nerve and muscle fibre), neurons and synapses, two divisions, cns: brain and spinal cord, pns: carries info from sensory receptors to cns, carries commands from. Cns to muscles, afferent pathways-carry sensory information to brain (ascending), efferent-carry commands to the muscles from the brain (descending)
